The possibility of an arc discharge between the electrons is prevented. This high-intensity heat melts and vaporizes the work material at the spot of beam impact. When the high-velocity beam of electrons strikes the workpiece, its kinetic energy is converted into heat. 2. The schematic arrangement of Electron Beam Machining (EBM) is shown in Fig. Nonetheless, traditional EBL is predominantly applicable to large-area planar substrates and often suffers from chemical contamination and complex processes for handling resists. Required fields are marked *. Holes of different sizes and shapes can be machined. Electron beam lithography (often abbreviated as e-beam lithography or EBL) is the process of transferring a pattern onto the surface of a substrate by first scanning a thin layer of organic film (called resist) on the surface by a tightly focused and precisely controlled electron beam (exposure) and then selectively removing the exposed or nonexposed regions of the resist in a solvent (developing). So, it becomes easy for the operator to observe the progress of the machining operation. Drilling of holes in pressure differential devices used in nuclear reactors, aircraft engines, etc. The focusing lens is used to focus the electrons at a point and reduces the electron beam up to the cross-sectional area of 0.01 to 0.02 mm diameter.
